I want to get all my that's inside . I wrote this code:
matchObj = re.search(r'<tr>(.*?)</tr>', txt, re.M|re.I|re.S)
but I only get the first group.
how can I get all groups?
Thanks in advance :)

Use an HTML parser. Can will never be smarter than the most dumb HTML parser.user2665694– user26656942012-12-11 15:51:34 +00:00Commented Dec 11, 2012 at 15:51

you should have at least tried "help(re)" match / findall are the basic components of re. Please research a bit before asking on SO>pranshus– pranshus2012-12-11 15:52:26 +00:00Commented Dec 11, 2012 at 15:52

findall
matchObj = re.findall(r'<tr>(.*?)</tr>', txt, re.M|re.I|re.S)
search only finds the first one in the given string.
you can read more about the different methods you can use in regex.
however, it looks like you are parsing HTML. why don't you use an HTMl parser?

yeah you should use
BeautifulSoup or somethingTo get more than one match use re.findall().
However, using regular expressions to parse HTML is going to get ugly and complicated fast. Use a proper HTML parser instead.
Python has several to choose from:
- ElementTree is part of the standard library
- BeautifulSoup is a popular 3rd party library
- lxml is a fast and feature-rich C-based library.
ElementTree example:
from xml.etree import ElementTree
tree = ElementTree.parse('filename.html')
for elem in tree.findall('tr'):
print ElementTree.tostring(elem)
BeautifulSoup example:
from bs4 import BeautifulSoup
soup = BeautifulSoup(open('filename.html'))
for row in soup.select('table tr'):
print row
